 ' Resume' is a reflection of your personality and attitude. 1.Resume should not be more than two pages. Human resources department don't have enough time to look at your huge menu cards , so make it simple. 2. You should not write on the heading as  resume or curriculum vitae . Instead of that write your full name in bold.    3.Highlight your educational achievements as per company requirement. e.g. Passed paper 1 & 2. 3. On the Second page, at the bottom, there should be your personal information. Following information should be there : Your full name    Email id     Date of Birth   Permanent address.   Contact number and alternate contact number.   Aadhar card and passport number . 4.Photo should be there in the first page. 5.Resume should be updated regularly . 6.Font size should be between 11 to 14 clearly . Do not use cursive font. 7.Cover letter should  always be address to HR manager . 8. There should be 1...

Conventional VOR/DME have one disadvantage in that they are land base and unable to navigate over coastal region. Long-range radio navigation system based on hyperbolic navigation where introduce in the 1940's to provide for en-route operations over oceanic and on populated areas.  Several hyperbolic system have been deployed  since, including Decca, omega and LORAN-C.  The operational use of omega and decca navigation system ceased in 1997 and 2000 respectively. And it was replaced by GPS and INS system. LORAN - C system are still very much available today as stand-alone system, they are also being proposed as a complimentary navigation aid for GPS.  the LORAN-C system is based on a master station and a numbers of secondary stations(slave), the use of very low frequency radio provides increased area of coverage.   Frequency : very low frequency (vlf) 10 -14 khz. System consists of ground-based fix master and several slave stations  (located at different ...

Dumping fuel from the aircraft (in flight)  is called jettisoning. On ground , it is called defuelling. Fighter planes are capable of refulling  in flight.Since commercial passenger aircraft carries passenger, they are not allowed to refuel during flight due to safety reasons. More ever, commercial planes have very big fuel tanks(in their wing) so they don't require in flight  refueling.They always carry additional fuel for holding or taxing. Every commercial pilot calculates their  usable fuel in his plane in the following manner : Departure to  Destination + 30 minute extra (for holding and taxing). If an aircraft has to do 'air turn back' (return to airport ) then the aircraft has to dump certain amount of fuel which is called jettisoning. It is calculated by flight management computer and executed by the pilot's manually   Pilots cannot dump fuel anywhere, they have to take permission from air traffic controllers.  after that they (ATC) will i...

We travel through bus, train or plane, we always look for a window seat so that we can enjoy the glimpse of the nature.   Nowadays, through web check in, we can choose our favorite seat. Some  passenger like window seat while some like aisle seat. But, if you are travelling on an airplane, there is something that you should always be very careful - it is called a 'window seat without a window '. Yes! It may sound weird, but it does exist.  This is because some electrical vertical conduits pass from that area. Unfortunately, if you select this seat through web check in or normal check in on the airport, then your journey will be a nightmare for you. There are some tactics through which you can prevent this seat being selected by you. So, Whenever you select a seat always check aircraft configuration. You can do it through the company website or in seat guru website.  Look for a special colors. If you find a red color on the window seat, then you aren't supposed t...

Selective availability of GPS   : GPS included a feature called selective availability that adds intentional, time varrying errors up to 10 metre horizontal and 30 metres vertically into the publicly available L1 signal. This was intended to deny an enemy the use of civilian GPS receiver for precision weapon guidance. The GPS can be used for the following purposes. 1. Differential GPS (DGPS) : for marine uses, maintained by the US coast guard. 2.WAAS (wide area of mentation system) . Extremely accurate navigation system developed by FAA. Provide service for all aircraft for all phase of the flight including and route navigation, airport departure and arrival. Particularly LNAV & VNAV in  low visibility operations. Currently,it only covers North america as there are no ground reference stations for this technology in other countries yet. 3.LAAS ( local area augmentation system)  all weather aircraft landing system (instrument landing system) used to replace conv...

GPS Operations: 1.The property of wave propagation can be used for satellite navigation purpose in the. 2. First, we need to know the exact position of satellite in orbit about the earth. 3.When the satellite transmitts radio wave to an observer on the earth surface  , the time delay between when the radio signal was transmitted and received provides the means of calculating the spherical range between the satellite and observer. 4.  Through second satellite, we can improve directional ambiguity.  5. Third satellite will improve all directional ambiguity and define our 2D dimensional position on the earth. 6. Fourth satellite will give us the 3D view as well as Latitude and longitude and altitude. 7.Once  the user's position has been calculated, the gps receiver can derive additional useful navigation information track,ground speed and drift angle. Space segment : Each satellite is installed with the ' four atomic clock' that are extremely accurate, typically ...

  1.Global positioning system(GPS) was invented in 1973 by United State Military , and referred to as ' Navstar'(navigation satellite with the timing and ranging ). 2.The system was initially developed for use by the us military. They were using this  satellite for surveillance purpose on neighboring countries. 3.The first satellite was launched in 1978 and full constellation was in place and operating by 1994 . 4. GPS is now widely available for use by many applications including aircraft navigation. 5. The system compromises a space segment, user segment and control segment .  6.The  control segment  consist of ground based transrecivers which monitors the satellite health.e.g. NASA, ISRO. 7.The  user segment  can be an Aircarft, any personnel. 8.The  space segment  consist of group of 24 Satellite. 9. 24 satellite (the space segment )in orbit around the earth send data via radio link that allows aircraft receivers (the user segment) ...
